IRVING A. WESTON, OF SYRACUSE, NEW YORK.

TRICYCLE.

SPECIFICATION forming part of Letters Patent No. 439,915, dated November4, 1890. Application filed February 2, 1888. Serial No. 262,799. (Nomodel.)

To all whom it may concern:

Be it known that I, IRVING A. WESTON, of Syracuse, county of Onondaga,in the State of New York. a citizen of the United States, have inventedcertain new and useful Improvements in Tricycles, of which the followingis a specification, reference being had to the accompanying drawings.

My invention relates to improvements in tricycles, the object being tomake the parts more simple and better adapted to stand the severe strainin propelling over rough roadways, in making the pedal-shaft support ina single piece, in attaching it securely yet adj ustably to the sidebars, and certain other functions and advantages, as will hereinafter beexplained.

With these ends in view my invention consists in certain features ofconstruction and combinations of parts, as will be hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, which form a part of thisspecification,Figure 1 is a side elevation of a tricycle, showing allthe parts in place. Fig. 2 is a plan view with the seat removed tobetter show the construction. Fig. 3 is a sectional end elevation takenon line X X of Fig. 4., and shows the pedal-shaft bearings attached tothe bars H H. Fig. 4 is a side elevation of the front part of a tricyclewith the neck and pedal-shaft bearin gs attached to side bars. Fig. 5 isa plan view showing the same parts.

A A are the main driving-wheels, and I the guide-wheel. The latter islocated in front of the driving-wheels and supported within the fork 'm,the stem of which is swiveled in the socket Z Z of the neck F.

The main frame consists of the two bars H H, which are attached to theaxle-support G at their rear ends and extend forward on each side of andare secured to the rear end of the neck F near their middle and again attheir forward ends, thus leaving the intervening space at which thepedal-shaft supportis attached.

The pedal-shaft support is made in a single piece, having the notches toreceive the side bars, and is secured to the bars by means of the boltK. The pedal-shaft support may be readily adjusted on the bars to takeup any slack in the drive-chain. By having the pedal-shaft support inone piece, having the two bearings a an integral therewith, the bearingsare always kept in line. Consequently friction is reduced and bearingswear evenly. The neck F is also made of a single piece of metal, ofgraceful design yet well calculated to strongly brace the steering-Wheeland front part of the machine.

By having the side bars H H, attached to the axle-support at their rearends, some distance apart and converging as they extend forward andattach to the neckF avery rigid frame is had and well calculated towithstand any lateral strain, as well as the work of the operator inpropelling.

The pedal-shaft sprocket-wheel and drivechain are low down and entirelybelow the frame of the machine. Thus the operator is free from danger ofsoiling or tearing the clothing, and also sits low, and danger offalling is avoided.

Having thus described my invention, what I claim, and desire to secureby Letters Patcut, is

1 In a tricycle, the side bars H H, attached to the axle-support attheir rear ends and extending forward on each side of and secured to theneck F at its rear end and again near its forward end, leavingtheintervening space and edges adapted to receive the pedal-shaftsupport, which is adj ustably secured thereto, all substantiallyasshown, and for the purpose set forth.

2. In a tricycle, the pedal-shaft support E, made in a single piece,having the two shaftbearings at the lower end of arms and provided atthe top with the slotways adapted to receive the edges of the barsand-adj ustably secured thereto, substantially as shown, and forthepurpose set forth.

In witness whereof I have hereunto set my hand this 31st day of January,1888.

IRVING A. 'WESTON. In presence of- J. O. EDDY, G. '1. S. Foorn.
